A vent is disposed in the rain-fly and is configured to allow ventilation into the internal volume when the rain-fly is in the closed configuration. Tensioning members are coupled to the base layer and are configured to be coupled to support members to suspend the apparatus off the ground.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of U.S. Provisional Application No. 61/754,762, filed Jan. 21, 2013 and entitled “Outdoor Shelter Ventilation System,” the entire contents of which are hereby incorporated by reference herein.

BACKGROUND

Embodiments described herein generally relate to outdoor shelter systems that include a ventilation system, and in particular to hammocks which include a ventilation system and are configured to be used in a hammock configuration or a bivy configuration.

Hammocks are primarily used as leisure items for relaxing. Conventional hammocks generally include a base which is suspended above the ground using tethers and supports thereby providing the user a relaxing platform to lie on. In some instances, hammocks are also used in place of a tent in outdoor trips (e.g., camping, hiking, hunting, alpine climbing, etc.), generally to increase comfort and to reduce overall weight to be carried. The functionality and practical usage of conventional hammocks can be severely limited in outdoor settings. For example, conventional hammocks do not provide any protection against insects or the weather (rain, wind, sun, etc.) which is necessary for comfort and safety in the outdoors. Often, a user has to carry a hammock, bug netting, a rain-fly or a tarp, suspension lines, and/or securement straps in the backpack as separate items. This significantly increases the weight, complexity, and storage volume requirements of the backpack. Furthermore, conventional hammocks almost always require two trees or an equivalent support structure from which the hammocks can be suspended to function. If such support structures are not available, conventional hammocks are not readily adaptable for use in a bivy configuration. In other words, while conventional hammocks may be used in a bivy configuration, they are not designed for it because they are not waterproof or weatherproof so they offer no protection from the environment. The use of a conventional hammock in a bivy configuration can be dangerous because of the environmental hazards like water, wind, temperature, etc. This limited functionality can severely limit the usefulness of conventional hammocks in outdoor environments where there is limited availability of support structures, for example, alpine environments.

As described above, conventional hammocks are open to the environment and do not provide any protection against insects and/or adverse weather conditions. Some known hammocks have built-in mosquito netting to protect a user from insects. Some known hammocks also include a separate rain tarp to protect the hammock from precipitation and rain. Generally, such rain tarps are tethered between two supports and suspended over the hammock. Despite the additional coverage provided by the rain-tarp, such systems are not waterproof in cases of fog, lateral rain, or high winds. Moreover, they add complexity to the gear, weight and volume to the backpack, and generally increase the cost of the outdoor shelter configuration.

Some known hammocks are configured to be used in a hammock configuration and a bivy configuration and can include an integrated rain-fly and/or bug netting material. However, many of these known hammocks require the use of an additional waterproof rain-fly for protection from precipitation. Such known hammocks generally have significantly higher mass and volume than their hammock and/or bivy counterparts. Another major limitation of such known hammocks is the lack of ventilation. This lack of ventilation can lead to build up of condensation in an internal volume of such known hammocks from the users body heat, sweat or breath, and can lead to oxygen deprivation (i.e., cerebral hypoxia) during use.

Thus, there is a need for improved outdoor shelter systems that can be used in a wide range of outdoor environments, are light weight, and can increase the level of comfort of the user

DETAILED DESCRIPTION

Embodiments described herein generally relate to outdoor shelter systems that include a ventilation system, and in particular to hammocks which include a ventilation system and are configured to be used in a hammock configuration or a bivy configuration. Embodiments of the outdoor shelter system described herein can provide a self contained waterproof, and/or windproof shelter that can be suspended off the ground as a hammock from trees, a rock wall, or an equivalent support structure, while also having the ability to be laid on the ground and used as a bivy in the absence of such support structures.

Embodiments of the outdoor shelter system described herein provide several advantages over conventional outdoor shelter systems, including: (1) providing protection against adverse weather (e.g., precipitation, rain, fog, snow, etc.) and/or insects; (2) ventilation allow air to flow through the outdoor shelter system in one or more planes while still maintaining the ability to protect the user from insects, precipitation and other elements of nature; (3) providing protection while decreasing condensation, reducing sentiments of claustrophobia, and increasing the comfort level of the user; (4) ability to be used in multiple configurations (i.e., it can be suspended between two supports (e.g., trees) to be used in a hammock configuration or laid on the ground to be used in a bivy configuration), while maintaining the ventilation through outdoor shelter system; (5) providing the comfort and lightweight nature of hammock camping along with the versatility, safety and weatherproof nature of a bivy; and (6) providing a self contained shelter that can be used in virtually any landscape without the need of additional tarps, netting, or support structures.

In some embodiments, an apparatus includes an elongate base layer that has a first end and a second end. A rain-fly having a first end and a second end is coupled to the base layer and configured to be spaced apart from the base layer such that the rain-fly and the base layer define an internal volume.

As used herein, the term “about” and “approximately” generally mean plus or minus 10% of the value stated, for example about 250 μm would include 225 μm to 275 μm, about 1,000 μm would include 900 μm to 1,100 μm.

As used herein, the term “bivy” and “bivy sack” (also known as a bivouac sack or bivvy) is a small, lightweight, waterproof outdoor shelter often used by hikers, climbers and others as an alternative to traditional tent systems. Essentially a bivy sack is a thin, waterproof fabric shell that is designed to slip over a sleeping bag, forming an effective barrier against wind and rain.

FIG. 1 shows a schematic block diagram of an outdoor shelter system 100 according to an embodiment. The outdoor shelter system 100 includes a base layer 110 and a rain-fly 120 coupled to the base layer 110. Optionally, a mesh material 130 is disposed between the base layer 110 and the rain-fly 120. A vent 140 is disposed in the rain-fly 120 to allow ventilation through the outdoor shelter system 100. Tensioning members 170 are coupled to the base layer 110, and optionally to the rain-fly 120. The tensioning members 170 can be configured to be coupled to support members to suspend the outdoor shelter system 100 in a first configuration (also referred to as “the hammock configuration”). The outdoor shelter system 100 is also operable in a second configuration (also referred to as “the bivy configuration”) in which the base layer 110 is disposed on a surface (e.g., the ground).

The base layer 110 has an elongated shape and includes a first end and a second end. The first end can be proximate to the head of a user lying on the base layer 110, and the second end can be proximate to the feet of the user. The first end and the second end of the base layer 110 can be disposed along a longitudinal axis of the outdoor shelter system 100. The base layer 110 can be formed from a strong and flexible material, for example, a fabric which can be waterproof, windproof, breathable, or any combination thereof. Such materials can include, for example, nylon, GORTEX®, any other suitable material or combination thereof. The base layer 110 is strong enough to bear the weight of the user when suspended in the hammock configuration or to be laid on a surface, for example, the ground in the bivy configuration, and still provide protection from precipitation, wind, insects and other elements.

In some embodiments, the first end and the second end of the base layer 110 can be looped over themselves to form a first suspension sleeve and a second suspension sleeve, respectively. The first and second suspension sleeves can be configured to provide a coupling mechanism for the tensioning members 170, as described in further detail herein. In some embodiments, the first end of the base layer 110 can be configured to be coupled to a first support member and the second end of the base layer 110 can be configured to be coupled to a second support member to suspend the outdoor shelter system 100 off the ground. In some embodiments, the first end and the second end of the base layer 110 can be coupled to suspension lines which are configured to be coupled to the first support and the second support to suspend the outdoor shelter system 100 of the ground.

In some embodiments, a plurality of guyline loops can also be disposed at the first end and the second end of the base layer 110. The guyline loops can be used to secure the outdoor shelter system 100 to the ground or other structures, for example, via guylines, to prevent the outdoor shelter system 100 from moving. For example, in the hammock configuration, the guyline loops can be used to stabilize the outdoor shelter system 100 from swaying from side to side by tying the guyline loops to tent stakes on the ground. Furthermore, in the bivy configuration, the guyline loops can be configured to provide additional securement to the ground and/or spread out the base layer 110.

In some embodiments, the base layer 110 can also include receiving members, for example, pockets, loops, bands, clips, VELCRO® straps, or any other suitable receiving member. The receiving members can be disposed on either side of the base layer 110 inline with a transverse axis of the base layer 110, and can be configured to receive ends of an arch support member, as described in further detail herein.

The rain-fly 120 includes a first end and a second end, and is coupled to the base layer 110. The rain-fly 120 can be formed from a strong and flexible material, for example, a fabric which can be water proof, windproof, breathable, or any combination thereof. Such materials can include, for example, nylon GORTEX®, any other suitable material or combination thereof. In some embodiments, the rain-fly 120 can be formed from the same material as the base layer 110. In some embodiments, the rain-fly 120 and the base layer 110 can be formed from different materials. At least a portion of the rain-fly 120 can be fixedly coupled to the base layer 110, for example, via sutures, adhesive, rivets, staples or any other suitable coupling means. The rain fly 120 is configured to be spaced apart from the base layer 110 such that the rain-fly 120 and the base layer 110 define an internal volume of the outdoor shelter system 100, within which the user can relax.

At least a portion of the rain-fly 120 can be moveable from an open configuration in which the internal volume can be accessed, to a closed configuration in which the internal volume is substantially sealed. For example, a releasable coupling mechanism such as, for example, a zipper, VELCRO®, buttons, or any other suitable releasable coupling mechanism can be disposed along a side or an edge of the rain-fly 120 and can, for example, traverse perpendicularly across the rain-fly 120 to the opposite side. In the open configuration, the rain-fly zipper can be unzipped and the rain-fly 120 folded to one side to allow the user easy access into the internal volume of the outdoor shelter system 100. Once inside, the user can close the rain-fly zipper to move the rain-fly 120 from the open configuration to the closed configuration, thus substantially sealing the user in the internal volume. The releasable coupling mechanism (e.g., a zipper) can be weatherproof to provide substantial sealing from precipitation and winds. In this manner, the outdoor shelter system 100 can provide the user shelter from precipitation and wind in the hammock configuration as well as in the bivy configuration.

In some embodiments, the outdoor shelter system 100 can also include an arch support member (not shown) configured to be coupled to the rain-fly 120 and to hold the rain-fly 120 spaced apart from the base layer 110, such that the outdoor shelter system 100 defines an internal volume in the hammock configuration and the bivy configuration. A first end and a second end of the arch support member can be removably coupled to the base layer 110, for example, disposed in the receiving members of the base layer 110 (e.g., a pocket) such that the arch support member is disposed along a transverse axis of the outdoor shelter system 100. In some embodiments, the arch support member can be coupled to the rain-fly using a releasable coupling mechanism such as, for example, VELCRO®, clips, hooks, rings, snaps, or any other suitable releasable coupling mechanism. In some embodiments, one or more sleeves can be disposed on the rain-fly 120. Each of the sleeves can define a lumen configured to receive at least a portion of the arch support member. The arch support member and the sleeves can be configured to cooperatively urge the rain-fly 120 to be spaced apart from the base layer 110 to define the internal volume. The arch support member can be formed from a strong and lightweight material, for example, metals (e.g., aluminum), plastics, metal reinforced plastics, polymers, any other suitable material or combination thereof. In some embodiments, the arch support member can be monolithically formed and can be flexible. In some embodiments, the arch support member can be formed from multiple pieces which can be assembled together to form the arch support member. In such embodiments, each piece of the arch support member can include an internal tether configured to pass through a lumen of each piece of the arch support member. The internal tether can be configured to tether together each piece of the arch support member, for example, to prevent misplacement of any one of the pieces of the arch support member. In some embodiments the rain-fly 120 can be spaced apart from the base layer 110 by coupling a first end of a suspending member, for example, a rope or a cord to a central portion of the rain-fly 120. A second end of the suspending member can be coupled to an over head support, for example, a tree, a rock, a hook, or any other suitable overhead support, thereby maintaining the rain-fly 120 spaced apart from the base layer 110.

In some embodiments, a mesh material 130 can optionally be disposed between the base layer 110 and the rain-fly 120. At least a portion of the mesh material 130 can be moveable between an open configuration and a closed configuration such that the mesh material 130 is configured to protect a user from insects when the rain-fly 120 is in the open configuration and the mesh material 130 is in the closed configuration. The mesh material 130 can be formed from any suitable material, for example, a bug net, a fish net, wire mesh, or any other suitable mesh material. A releasable coupling mechanism such as, for example, a zipper, VELCRO®, buttons, or any other suitable releasable coupling mechanism can be disposed along a side or an edge of the mesh material 130 which can, for example, traverse perpendicularly across the mesh material 130 to the opposite side. In some embodiments, the mesh material 130 releasable coupling mechanism can follow the same track as the rain-fly 120 releasable coupling mechanism. In some embodiments, the mesh material 130 releasable coupling mechanism can also be weatherproof. In the open configuration, the mesh material 130 can be rolled to one side out of the way of the user. In the closed configuration, the mesh material 130 zipper can be closed thereby providing a bug net over the user's head while still allowing the user to observe the outside environment.

The vent 140 can be disposed in the rain-fly 120 and is configured to allow ventilation into the internal volume defined by the outdoor shelter system 100 when the rain-fly 120 is in the closed configuration. The vent 140 can be any shape or size, for example, rectangle, square, circle or any other suitable shape. In some embodiments, the vent 140 can include a mesh material, for example, a bug net coupled (e.g., sown) to the rain-fly 120. In some embodiments, the vent 140 can be disposed at the first end of the rain-fly 120. In some embodiment, the vent 140 can be a first vent 140 and a second vent can be disposed at the second end of the rain-fly 120. The first vent 140 and the second vent can be operative to provide cross ventilation through the internal volume defined by the outdoor shelter system 100. In some embodiments, flaps can be disposed beneath the first vent 140 and/or the second vent to close the vents in adverse weather conditions.

A rigid member can be disposed along a top edge of the vent 140 and can be configured to maintain the vent in an expanded configuration. The rigid member can include, for example, a spreader bar, a stick, a rod, a taut rope, a cable, or any other suitable rigid member. In some embodiments, the rigid member can include a spreader bar, which can be a hollow rod that defines a lumen. The rigid member can be formed from a strong and rigid material, for example, metals (e.g., aluminum), plastics, polymers, wood, any other suitable material or combination thereof. The rigid member can have a cross section which is circular, square, rectangular, oval, polygonal, or any other suitable cross section. In some embodiments, the rigid member can be disposed in a rigid member sleeve disposed along the top edge of the vent 140. The rigid member can be configured to maintain the vent 140 in an expanded configuration by preventing the vent 140 from collapsing, folding, or otherwise being obstructed. In some embodiments, the rigid member can also be used to couple one or more of the tensioning members 170 to the rain-fly 120, as described in further detail herein.

In some embodiments, a dam can be disposed along a bottom edge of the vent 140 to prevent water from passing through the vent 140 into the internal volume defined by the outdoor shelter system 100. In some embodiments, the dam can include, for example, a fabric sheet, a plastic sheet, a polymer sheet, nylon, GORTEX®, or formed from any other suitable material, which is coupled to a bottom edge of the vent 140. In some embodiments, the first end and the second end of the rain-fly 120 can be folded over and coupled to the bottom edge of the vent 140 (e.g., sutured) to form the dam.

In some embodiments, the rain-fly 120 can also include a gable vent, also referred to herein as “medial vent”, and which can be disposed proximate to a medial portion of the rain-fly 120. In some embodiments, the rain-fly 120 can include a single medial vent. In some embodiments, the rain-fly 120 can include a plurality of medial vents. For example, a first medial vent and a second medial vent can be disposed in the rain-fly 120 substantially opposite to each other. In some embodiments, the one or more medial vents can be disposed proximate to the head of the user. In such embodiments, the medial vents can provide additional ventilation near the face of the user for added comfort, reduce condensation caused by exhalations, and reduce any sentiments of claustrophobia. The medial vent can be triangular, square, rectangular, circular, or any other suitable shape or size. The medial vent can be formed from a mesh material, for example, a bug net, a fish net, a wire mesh, or any other suitable mesh or porous material.

An occlusion member can be disposed below the one or more medial vents. The occlusion member can be configured to be moveable between a first configuration in which the medial vent is closed, and a second configuration in which the medial vent is open. The occlusion member can be configured such that it is folded in the first configuration and folded in the second configuration. In some embodiments, the occlusion member can be fastened temporarily with, for example, a zipper, snaps, clamps, hook-and-loop material, etc., in the first configuration and then released from the temporary fastener in the second configuration. The occlusion member can be configured to redirect water passing through the medial vent away from the internal volume of the outdoor shelter system 100 when the occlusion member is in the first configuration.

The outdoor shelter system 100 includes tensioning members 170 which are coupled to the base layer 110 and optionally, to the rain-fly 120. For example, the outdoor shelter system 100 can include a first tensioning member 170 coupled to the first end of the base layer 110 and configured to be coupled to a first support member. The outdoor shelter system 100 can also include a second tensioning member 170 coupled to the second end of the base layer 110 and configured to be coupled to a second support member. The first tensioning member 170 and the second tensioning member 170 can be operable to keep the outdoor shelter system 100 suspended off the ground (i.e., in the hammock configuration) when coupled to the first and second support members. The first and second support members can include, for example, trees, rocks, poles, or any other support member between which the outdoor shelter system 100 can be suspended. In some embodiments, the tensioning members 170 can be configured to be secured to the ground to enable use of the outdoor shelter system 100 in the bivy configuration. The tensioning members 170 can be made from a strong but stretchable material, for example, a bungee cord, elastic rope, a resistance band, rubber band, or any other suitable material. The tensioning members 170 can also be made from a strong non-stretchable (i.e., “static”) material that can be adjusted, for example, with a tension lock.

In some embodiments, the tensioning members 170 can be coupled to the ends of the base layer 110 by looping through the lumen defined by the suspension sleeves disposed at the first end and the second end of the base layer 110, as described herein. In some embodiments, the tensioning members 170 can be coupled to a suspension member, for example, a belt, a truss, a connector, or any other suitable suspension member, coupled to the first end of the base layer 110 and/or to the second end of the base layer 110. In some embodiments, the tensioning members 170 can be configured to be coupled to the support members. In some embodiments, one or more suspension lines can be coupled to the tensioning members 170. The suspension lines can then be coupled to the support member for suspending the outdoor shelter system 100 off the ground. A coupling member, for example, a clip, a clamp, a hook, a ring, or any other coupling mechanism can be used to couple the tensioning member 170 to the suspension lines. The tensioning members 170 can be configured to exert a tensile force on either direction of the base layer 110, for example, to balance the base layer 110 in the hammock configuration (i.e., prevent flipping over), and/or enable lateral spreading of the base layer 110 in the hammock and the bivy configuration.

In some embodiments, a third tensioning member 170 can be coupled to the first end of the rain fly 120. For example, the third tensioning member 170 can be coupled to the rigid member (e.g., looped through a lumen of the rigid member) disposed along the top edge of the vent 140 disposed at the first end of the rain-fly 120. The third tensioning member 170 can be configured to be coupled to the first support member, the first tensioning member 170, or to the suspension line coupled to the first support member via the coupling member. Similarly, a fourth tensioning member 170 can be coupled to the second end of the rain-fly 120. For example, the fourth tensioning member 170 can be coupled to a rigid member (e.g., looped through a lumen of the spreader bar) disposed along a top edge of a second vent disposed at the second end of the rain-fly 120. The fourth tensioning member 170 can be configured to be coupled to the second support member, the second tensioning member 170, or to the suspension line coupled to the second support member. The third tensioning member 170 and the fourth tensioning member 170 can be configured to apply a tensioning force on the first end and the second end of the rain-fly 120. This tensioning force can maintain the rain-fly in a taut configuration, and/or prevent the vent 140 (e.g., the first vent and/or the second vent) from falling over towards the base layer 110, thereby keeping the vent 140 in an open configuration. Furthermore, the tensioning force can also urge the vent 140 (e.g., the first vent and/or the second vent) to be inclined at an angle towards the supports, such that a ledge is defined over the vent 140. The ledge can prevent water from falling over and passing through the vent 140 into the internal volume defined by the outdoor shelter system.

The outdoor shelter system 100 is configured to be lightweight, for example, have a weight of less than about three pounds, less than about two and a half pounds, or less that about two pounds. The outdoor shelter system 100 can be configured to be rolled and disposed in a housing, for example, a bag, a sleeve, or a sack, or can be secured via straps.

Having described above various general principles, several embodiments of these concepts are now described. These embodiments are only examples, and many other configurations of an outdoor shelter system are contemplated.

In some embodiments, an outdoor shelter system can include a base layer and a rain-fly. Referring now to FIGS. 2-12, an outdoor shelter system 200 includes a base layer 210, a rain-fly 220, a mesh material 230, a first vent 240, a second vent 250, a first tensioning member 271, and a second tensioning member 272. The outdoor shelter system 200 is operable to be used in a first configuration (also referred to as “hammock configuration”) in which the outdoor shelter system 200 is suspended off the ground as shown in FIGS. 2-6, and a second configuration (also referred to as “the bivy configuration”) in which the base layer 210 is disposed on a surface (e.g., the ground) as shown in FIG. 12 and described in further detail herein.

The base layer 210 has an elongate shape and includes a first end 211 and a second end 212. The first end 211 can be proximate to the head of a user lying in the outdoor shelter system 200, and the second end 212 can be proximate to the feet of the user such that the first end 211 and second end 212 are disposed along a longitudinal axis A_(L) of the outdoor shelter system 200. The base layer 210 can be formed from a flexible material, for example, a fabric which can be waterproof, windproof, breathable, or any combination thereof. Such materials can include, for example, nylon, GORTEX®, any other suitable material or combination thereof. As shown in FIG. 2 and FIG. 10, the first end 211 of the base layer 210 is looped over itself to form a first suspension sleeve 214 defining a first lumen 215. Similarly, the second end 212 of the base layer 210 is also looped over itself to define a second suspension sleeve 216 defining a second lumen 217 (FIGS. 5 and 6). The first suspension sleeve 214 and the second suspension 216 can be configured to provide a coupling mechanism for the first tensioning member 271 and the second tensioning member 272, respectively, as described in further detail herein. While shown as having a first tensioning member 271 and a second tensioning member 272, in some embodiments, the outdoor shelter system 200 does not include tensioning members. In such embodiments, the first end 211 can be coupled to a first support member and the second end 222 of the base layer 200 can be coupled to the second support member, or alternatively, the first end 211 and the second end 212 of can be coupled to suspension lines which can be coupled to the first support member and the second support member.

The outdoor shelter system 200 includes receiving members 218 disposed on both sides of the base layer 210 along a transverse axis A_(T) of the outdoor shelter system 200. Each of the receiving members 218 can be configured to receive an end of an arch support member 228, as described in further detail herein. The receiving members 218 can include, for example, pockets, loops, bands, clips, or any other suitable receiving member. A plurality of guyline loops 219 are disposed at the first end 211, the second end 212, and each side of the base layer 210. The guyline loops 219 can be configured to secure the outdoor shelter system 200 to the ground or other structures, for example, via guylines and prevent the outdoor shelter system 200 from moving (e.g., in high winds). For example, in the hammock configuration (FIGS. 2-6), the guyline loops 219 can be used to stabilize the outdoor shelter system 200 from swaying by coupling guylines to the guyline loops 219, and securing the guylines to the ground (e.g., secured to tent stakes disposed in the ground). Furthermore, in the bivy configuration (shown in FIG. 12), the guyline loops 219 can be coupled with tent stakes disposed in the ground, for example, to provide additional securement of the base layer 210 to the ground, and/or to spread out the base layer 210 (i.e., analogous to a tent or a bivy sack).

The rain-fly 220 includes a first end 221 and a second end 222, and is coupled to the base layer 210. The rain-fly 220 can be formed from a flexible material, for example, a fabric which can be waterproof, windproof, breathable, or any combination thereof. Such materials can include, for example, nylon, GORTEX®, any other suitable material or combination thereof. In some embodiments, the rain-fly 220 can be formed from the same material as the base layer 210. In some embodiments, the rain-fly 220 and the base layer 210 can be formed from different materials. The rain-fly 220 can be coupled to the base layer 210 via sutures, adhesives, rivets, or any other suitable coupling means.

The rain-fly 220 is configured to be spaced apart from the base layer 210 such that the rain-fly 220 and the base layer 210 define an internal volume of the outdoor shelter system 200 within which the user can relax. A plurality of sleeves 226 are disposed on the rain fly 220 inline with the transverse axis A_(T) of the outdoor shelter system 200. Each of the plurality of sleeves 226 defines a lumen 227 configured to receive at least a portion of the arch support member 228. A first end and a second end of the arch support member 228 can be disposed in the receiving members 219 disposed on either side of the base layer 210. The sleeves 226 and the arch support member 228 are configured to cooperatively urge the rain-fly to be spaced apart from the base layer 210 to define the internal volume of the outdoor shelter system 200. While shown as including sleeves 226, in some embodiments, the outdoor shelter system 200 can include any suitable mechanism to receive and engage at least a portion of the arch support member 228. Such mechanisms can include, for example, VELCRO® straps, hooks, clips, rings, bands, or any other suitable mechanism.

The arch support member 228 can be formed from a strong but light-weight material such as, for example, metals (e.g., aluminum), plastics, polymers, metal reinforced plastic, any other suitable material or combination thereof. In some embodiments, the arch support member 228 can be monolithically formed. In such embodiments, the arch support member 228 can be flexible. In some embodiments, the arch support member 228 can be formed from multiple pieces which can be assembled together to form the arch support member 228. In such embodiments, each piece of the arch support member 228 can include, for example, an internal tether which can, for example, pass through a lumen of each piece of the arch support member 228. The internal tether can be configured to tether together each piece of the arch support member 228, for example, to prevent misplacement of any piece of the arch support member 228 when it is in a disassembled configuration.

At least a portion of the rain-fly 220 is moveable between an open configuration (FIGS. 5 and 6) in which the internal volume can be accessed, to a closed configuration (FIGS. 2-4) in which the internal volume is substantially sealed. As shown in FIGS. 2-6, a rain-fly zipper 224 is disposed along a side of the rain-fly 220 which traverses across the rain-fly 220 to the opposite side. The rain-fly zipper 224 can be weatherproof to provide substantial sealing against precipitation or wind. In some embodiments, VELCRO®, buttons or any other suitable releasable coupling mechanism can be used. In the open configuration, the rain-fly zipper 224 can be unzipped and the rain-fly 220 folded to one side to allow the user to access to the internal volume defined by the outdoor shelter system 200. Once inside, the user can close the rain-fly zipper 224 to move the rain-fly 220 into the closed configuration, thereby substantially sealing the user in the internal volume.

As shown in FIGS. 5 and 6, a mesh material 230 is disposed between the base layer 210 and the rain-fly 220. The mesh material 230 can include, for example, a bug net, a fish net, a wire mesh, any other suitable material or a combination thereof. At least a portion of the mesh material 230 is moveable between a closed configuration (FIG. 5) and an open configuration (FIG. 6). A mesh material zipper 234 or any other suitable releasable coupling mechanism (e.g., VELCRO®, buttons, etc.) is disposed along a side of the mesh material 230 and traverses perpendicularly across the mesh material 230 to the opposite side. The mesh material zipper 234 can follow the same path as the rain-fly zipper 224. In some embodiments, the mesh material zipper 234 can also be weatherproof. In the open configuration, the mesh material zipper 234 can be unzipped and the mesh material 230 folded or rolled to one side out of the way of the user. In the closed configuration, the mesh material zipper 234 can be closed urging the mesh material 230 into its closed configuration, as shown in FIG. 6. In this manner, the mesh material 230 can provide a bug net over the user when the rain-fly 220 is in its open configuration, and still allow the user to observe the outside environment while being protected from insects.

In some embodiments, the first vent 240 is disposed at the first end 221 of the rain-fly 220 and the second vent 250 (FIGS. 5 and 6) is disposed at the second end 222 of the rain-fly 220. The first vent 240 and the second vent 250 are operative to provide cross ventilation through the internal volume defined by the outdoor shelter system 200. While shown as being rectangular, the first vent 240 and the second vent 250 can have any shape or size, for example, square, triangular, circular, oval, or a polygon. In some embodiments, the first vent 240 and the second vent 250 can include a mesh material, for example, a bug net sown to the first end 221 and the second end 222 of the rain-fly 220, respectively. In some embodiments, flaps can be disposed beneath the first vent 240 and/or the second vent 250. The flaps can be configured to be moveable between an open configuration in which the first vent 240 and/or the second vent 250 are open, and a closed configuration in which the first vent 240 and/or the second vent 250 are closed. In some embodiments, the open area of the first vent 240 and the second vent 250 can be dynamically controlled to control the airflow through the internal volume defined by the outdoor shelter system 200.

As shown in FIG. 10, a spreader bar 242 is disposed along a top edge of the first vent 240. The spreader bar 242 is disposed inside a lumen defined by a spreader bar sleeve 229 disposed along a top edge of the first vent 240 at the first end 221 of the rain-fly 220. While shown as having a spreader bar, any other suitable member can be used such as, for example, a rod, a stick, a taut rope, a cable, any other suitable rigid member or combination thereof. In some embodiments, the first end 221 of the rain-fly 220 can be folded over itself into a loop to define the spreader bar sleeve 229. In some embodiments, the spreader bar 242 can be coupled to the first end 221 of the rain-fly 220 using any suitable means, for example, via an adhesive, sutures, rivets, bolts, screws, or any other suitable coupling means. The spreader bar 242 can be formed from a strong, rigid, and light weight material, for example, a metal (e.g., aluminum), or plastic. The spreader bar 242 can be configured to maintain the first vent 240 in an expanded configuration by preventing the first vent 240 from collapsing, folding, creasing, or otherwise being obstructed. The spreader bar 242 can be a hollow rod such as, for example, a metal (e.g., aluminum) rod or a plastic rod, which defines a lumen 243 configured to receive at least a portion of a third tensioning member 273, as describe in further detail herein. In some embodiments, the spreader bar 242 can be a first spreader bar and a second spreader bar (not shown) can be disposed along a top edge of the second vent 252. The second spreader bar can be disposed in the lumen of a spreader bar sleeve disposed at the second end 222 of the rain-fly 220 along a top edge of the second vent 250. Similar to the first spreader bar 242, the second spreader bar can be configured to maintain the second vent 250 in an expanded configuration. The second spreader bar can also define a lumen configured to receive at least a portion of a fourth tensioning member 274, as described in further detail herein.

A first dam 244 is disposed along a bottom edge of the first vent 240 and a second dam 254 is disposed along a bottom edge of the second vent 250. The first dam 242 and the second dam 254 are disposed such that a surface of the first dam 244 and the second dam 254 is parallel to a surface of the first vent 242 and the second vent 252, respectively. The first dam 244 and the second dam 254 can be formed from a flexible, light weight, and waterproof material, for example, a waterproof fabric, a plastic sheet, a polymer sheet, any other suitable material or combination thereof. In some embodiments, at least a portion of the first end 221 and the second end 222 of the rain-fly 220 can be folded over to form the first dam 252 and/or the second dam 254. Each of the first dam 244 and the second dam 254 can be configured to prevent water from passing through the first vent 240 and the second vent 250, respectively into the internal volume defined by the apparatus 200. For example, the first dam 244 and the second dam 254 can prevent rain water or precipitation running down the first tensioning member 271 and the second tensioning member 272, from passing through the first vent 240 and the second vent 250, respectively.

In some embodiments, the first dam 244 and the second dam 254 can be coupled to the first end 211 and the second end 212 of the base layer. FIGS. 11A-C show a method of coupling the first dam 244 within a fold of the suspension sleeve 214 disposed at the first end 211 of the base layer 210. FIG. 11A shows a top view and FIG. 11B shows a side perspective view of the first end 211 of the base layer 210. As shown in FIG. 11A, the base layer 210 is laid out flat and the first end 211 of the base layer 210 is folded over itself A bottom edge of the dam 244 is disposed between the fold, and the dam 244 is then coupled at the fold by the seam S (e.g., a suture or adhesive). In this manner, the suspension sleeve 214 is formed with the bottom edge of the dam 244 coupled to the fold of the suspension sleeve 214. FIG. 11C shows, the first suspension sleeve 214 and the first dam 244 in the hammock configuration. The first tensioning member 271 is disposed in the lumen 215 of the first suspension sleeve 214 and exerts a tensioning force on the first suspension sleeve 214. This can cause the first suspension sleeve 214 to squeeze, pleat, or otherwise scrunch, thereby urging the first dam 244 to also squeeze, pleat, or otherwise scrunch. Even though the first dam 244 can be squeezed, pleated, or otherwise scrunched in the hammock configuration, the first dam 244 can still prevent water from passing through the first vent 244. The second dam 254 can be disposed at the second end 212 of the base layer 210 in substantially the same fashion as the first dam 244.

The rain-fly 220 also includes a first gable vent 260 a and a second gable vent 260 b (collectively referred to as “the gable vents 260”). The gable vents 260 are disposed on either side of the longitudinal axis A_(L) of the outdoor shelter system 200 and proximate to the head of the user accessing the internal volume of the outdoor shelter system 200. The gable vents 260 can provide additional ventilation near the head of the user, thereby increasing the comfort level of the user and reducing sentiments of claustrophobia. While shown as being triangular, the gable vents 260 can have any shape, for example, square, rectangular, circular, etc. The gable vents 260 can be formed from a mesh material, for example, a bug net, a fabric mesh, a wire mesh or any other suitable mesh material. In some embodiments, the gable vents 260 can be formed from the same material as the first vent 240 and/or the second vent 250.

As shown in FIG. 6, a first occlusion member 262 a and a second occlusion member 262 b (collectively referred to as “the occlusion members 262”) is disposed below first gable vent 260 a and the second gable vent 260 b respectively. For example, a bottom edge of the occlusion members 262 can be coupled to a bottom edge of the gable vents 260. The occlusion members 262 are configured to be movable between a first configuration in which the gable vents 260 are open, and a closed configuration in which the gable vents 260 are closed. The occlusion members 262 are configured to be folded in the closed configuration and unfolded in the open configuration. FIG. 7A shows an exterior view and FIG. 7B shows an interior view of the first occlusion member 262 a in the closed configuration. The first occlusion member 262 a includes a first seam 265 a and a second seam 266 a such that the first occlusion member 262 a can be folded about the first seam 265 a and the second seam 266 a to provide a relatively flat occluding surface beneath the first gable vent 260 a. In this manner, the occlusion members 262 can prevent wind, water passing through the gable vents 260 from entering into the internal volume of the outdoor shelter system 200. Securing members 264 a, for example, VELCRO® straps or buttons are disposed on the surface of the first occlusion member 262 a which can be engaged to maintain the first occlusion member 262 a in the closed configuration.

The occlusion members 262 are configured to redirect water passing through the gable vents 262 away from the internal volume defined by the outdoor shelter system 200 when the occlusion members 262 are in the open configuration. FIG. 8A shows an exterior view, FIG. 8B shows an interior view, and FIG. 9 shows an inline view of the first occlusion member 262 a in the open configuration. In the open configuration, the first occlusion member 262 a (and the second occlusion member 262 b) is disposed such that at least a portion of the surface of the first occlusion member is inclined towards the bottom edge of the first gable vent 260 a. Droplets of water W, for example, rain water, can pass through the gable vent 260 a as shown by the arrow B (FIGS. 8A and 8B; FIG. 9) and strike a surface of the first occlusion member 262 a which faces the first gable vent 260 a. Since the surface of the first occlusion member 262 a is inclined towards the gable vent 260 a, it redirects the water droplets away from the internal volume of the outdoor shelter system 200, as shown by the arrow C (FIGS. 8A and 8C; FIG. 9). In this manner, the occlusion members 262 can be maintained in the open configuration during rain fall to provide ventilation but prevent any rain water from entering into the internal volume defined by the outdoor shelter system 200.

The first tensioning member 271 is coupled to the first end 211 of the base layer 210 and the second tensioning member 272 is coupled to the second end 212 of the base layer 210. The first tensioning member 271 and the second tensioning member 272 can be formed from a strong but stretchable material, for example, a bungee cord, an elastic rope, a resistance band, a rubber band, or any other suitable material. As shown in FIG. 1 and FIG. 10, at least a portion of the first tensioning member 271 is disposed in the lumen 215 defined by the first suspension sleeve 214. Similarly, at least a portion of the second tensioning member 272 is disposed in the lumen 217 of the second suspension sleeve 216. In this manner, the first tensioning member 271 and the second tensioning member 272 are coupled to the first end 211 and the second end 212 of the base layer 210. While shown as coupled to the first suspension sleeve 214 and the second suspension sleeve 216, in some embodiments, a suspension member such as, for example, a belt, a truss, a connector, or any other suitable suspension member can be coupled to the first suspension sleeve 214 and/or the second suspension sleeve, or to the first end 211 and the second end 212 of the base layer 210. In such embodiments, the suspension member can be configured to couple the first tensioning member 271 and the second tensioning member 272 to the first end 211 and the second end 212 of the base layer 210, respectively.

The first tensioning member 271 and the second tensioning member 272 are configured to be coupled to a first support member and a second support member (collectively referred to as “the support members”) and operable to suspend the outdoor shelter system 200 off the ground (i.e., in the hammock configuration). The support members can include, for example, trees, rocks, poles, any other suitable support members, or combination thereof. As shown in FIGS. 2-6, the first tensioning member 271 is coupled to a first coupling member 275 and the second tensioning member 272 is coupled to a second coupling member 276. The first coupling member 275 and the second coupling member 276 can include, for example, a clip, a clamp, a hook, a ring, any other suitable coupling member or combination thereof. A first suspension line 277 and a second suspension line 278 are also coupled to the first coupling member 275 and the second coupling member 276, respectively. The first suspension line 277 and the second suspension line 278 are configured to be coupled to the first support member and the second support member to suspend the outdoor shelter system 200 off the ground. In some embodiments, the first tensioning member 271 and the second tensioning member 272 can be configured to be coupled to the first support and the second support, respectively such that the suspension lines are not required. The first tensioning member 271 and the second tensioning member 272 can be configured to exert a tensile force on the first end 211 and the second end 212 of the base layer 210, for example, to balance the outdoor shelter system 200 in the hammock configuration (e.g., prevent flipping over), and/or to spread out the base layer 210.

As described herein, the third tensioning member 273 is coupled to the first end 221 of the rain-fly 220 and the fourth tensioning member 274 is coupled to the second end 222 of the rain-fly 220. As shown in FIG. 10, at least a portion of the third tensioning member 273 is disposed in the lumen 243 defined by the spreader bar 242. Similarly, the fourth tensioning member 272 can be disposed in a lumen defined by a second spreader bar disposed at the second end 222 (e.g., disposed in a second spreader bar sleeve) of the rain-fly 220. The third tensioning member 273 and the fourth tensioning member 274 can be formed from substantially the same material as the first tensioning member 271 and the second tensioning member 272. The third tensioning member 273 and the fourth tensioning member 274 are configured to be coupled to the first coupling member 275 and the second coupling member 276. In some embodiments, the third tensioning member 273 and the fourth tensioning member 274 can be configured to be coupled to the first support member and the second support member respectively, or the first tension member 271 and the second tensioning member 272, respectively. The third tensioning member 273 and the fourth tensioning member 274 can be configured to apply a tensioning force on the first end 221 and the second end 222 of the rain-fly 220. The tensioning force can urge the rain-fly 220 to be taut, and/or prevent the first vent 240 and the second vent 250 from falling over towards the base layer 210, thereby keeping the first vent 240 and the second vent 250 in the open configuration. Furthermore, the tensioning force can also urge the first vent 240 and the second vent 250 to be inclined towards the first support member and the second support member respectively, such that a ledge is defined over the first vent 240 and the second vent 250. The ledge can prevent water (e.g., rain water) from falling over and passing through the first vent 240 and/or the second vent 250, thereby allowing a user to keep the first vent 240 and the second vent 250 open during rain fall.

As described herein, the outdoor shelter system 200 is operable in the first configuration (i.e., the hammock configuration) in which the base layer 210 and thereby, the outdoor shelter system 200 is suspended off the ground, and the second configuration (i.e., the bivy configuration) in which the base layer 210 is disposed on a surface, for example, the ground. In the hammock configuration, the first tensioning member 271 and the second tensioning member 272 are configured to be coupled to the first support member and the second support member, for example, via the first suspension line 277 and the second suspension line 278 (FIGS. 2-6), as described herein. FIG. 12 shows the outdoor shelter system 200 in the bivy configuration. In the bivy configuration, the base layer 210 is disposed on the ground. The first tensioning member 271 and the third tensioning member 273 are coupled to a first securing member 281 (e.g., a tent stake) which is secured to the ground. Similarly the second tensioning member 272 and the fourth tensioning member 274 are coupled to a second securing member (e.g., a tent stake) 282 which is also secured to the ground. In the bivy configuration, the first tensioning member 271 and the second tensioning member 272 exert a tensile force on the base layer 210 to maintain the base layer 210 in a spread configuration. Furthermore, the guyline loops 219 can also be secured to the ground via guylines 284 and/or securing members to maintain the base layer 210 in the spread configuration. Thus the base layer 210 can provide a surface which is substantially free from creases or folds, for the user to lie on.

Furthermore, in the bivy configuration, the third tensioning member 273 and the fourth tensioning member 274 can exert a tensile force on the first end 221 and the second end 222 of the rain-fly to keep the rain-fly 220 taut and/or to prevent the first vent 240 and the second vent 250 from falling over towards the base layer, thereby keeping the first vent 240 and the second vent 250 in their open configuration. The tensioning force can also urge the first vent 240 and the second vent 250 to be inclined towards the first support member and the second support member respectively, such that a ledge is defined over the first vent 240 and the second vent 250. The ledge can prevent water (e.g., rain water) from falling over passing through the first vent 240 or the second vent 250, thereby allowing a user to keep the first vent 240 and the second vent 250 open during rain fall, in the bivy configuration. Moreover, the arch support member 228 and the sleeves 226 can hold the rain-fly 220 spaced apart from the base layer 210 in the bivy configuration. This prevents the rain-fly 220 from falling towards the base layer 210, thus maintaining the internal volume defined by the outdoor shelter system 200 in the bivy configuration.

Any of the components included in the outdoor shelter system 200 can be light weight such that the overall weight of the outdoor shelter system 200 is less than about 2 pounds. The outdoor shelter system 200 can be configured to be rolled up into a compact assembly which can easily fit within a backpack. In some embodiments, straps can be included in the outdoor shelter system 200 to maintain it in the rolled up configuration. In some embodiments, a housing such as, for example, a bag, a sack, or a sleeve, can be provided for housing the outdoor shelter system 200 in the rolled up configuration.
